Parts of Speech Review

Inside the case file

Parts of speech review for 4th grade and 5th grade, built as ten no prep CSI Mini Mystery Detective cases. These grammar worksheets cover prepositions and the objects of prepositions, relative pronouns and relative adverbs, conjunctions, interjections, and progressive and perfect verb tenses, with two mixed review cases to finish. Every answer is a word students find or form inside a full sentence, so this grammar practice works on the language students actually read and write. Use these parts of speech activities for ELA centers, morning work, homework, test prep, sub plans and early finishers, with an answer key for every case. The night train theme fits any time of year. Just print and go.

Fourth and fifth grade grammar asks students to see how words work together, and every case in this pack is built around that. Students find the object of a preposition, name the noun a relative pronoun describes, or write the right -ing form or past participle, then cross off the matching suspect. Every page is self-marking, so the class can work through a case on their own while you meet with a group.

When to Use This Resource

Each case takes one grammar skill at a time, so you can teach prepositions on Monday, hand out The Dining Car Caper on Tuesday and The Vanished Violin the day after. The relative pronoun and relative adverb cases make students look at the noun being described, which is where real understanding shows. The two mixed review cases work well as a grammar check before a unit test or state testing. Use it for ELA centers and literacy rotations, morning work, small group grammar lessons, homework, test prep, sub plans, early finishers, homeschool lessons, and back to school or end of year review.

Grade Levels

Written for 4th grade and 5th grade. Relative pronouns, relative adverbs, progressive tenses and prepositional phrases are 4th grade skills, and conjunctions, interjections and perfect tenses arrive in 5th grade, so one pack covers both years. It also makes a quick grammar review for 6th graders.
